After leaving the interrogation room, Han Bin checked the interrogation records again.
On the surface, Ma You Cai's confession made sense, but after careful analysis, it looked like a thesis.
Theoretically, it made sense, but in reality, it was extremely difficult. Ma Youcai had been with the other two suspects for a long time, so it was impossible for him not to have found some clues.
Ma You Cai's confession was probably prepared in advance for the judge.
He showed a cooperative attitude. Although they knew that there was something wrong with him, it was hard to convict him without concrete evidence.
Han Bin pondered for a moment and ordered, "Bao Xing, call a few team members. We're going out for a while."
"Captain Han, where are we going?"
"Xiaoxuan Village."
…
Xiaoxuan Village was located in the northern suburbs of Spring City.
Han Bin and the others drove to the south of the village. Not far away, there was a house with a seal.
Rao Jianguo pointed at the house with the seal and said, "Captain Han, that house is the suspect's lair."
Han Bin looked around but didn't see any obvious surveillance cameras.
Tao Yuanliang removed the seal and unlocked the door with the key. The group walked in.
The courtyard was not big and was overgrown with weeds. There were only a few rooms in the west and north.
Rao Jianguo explained, "There's a lot of junk in the west room, but there's no sign of living here. There are signs of living in the north house, and there's a cellar in the northwest corner of the yard. It's very likely that it was used to hold hostages. "
Han Bin nodded and walked around the west room. Just as Rao Jianguo had said, it was a messy storeroom.
The north room had a livable environment, but it was very clean. It should have been cleaned up by the technical department of Spring City.
After that, the group went down to the cellar. There was a lamp on the right side of the cellar, and it was quite bright after it was switched on.
There were not many things in the cellar, only a bed and a vat.
Rao Jianguo explained, "The suspect rented this house from the villagers, and the vat was placed there by the villagers. It used to store things. The villager had never seen the bed before.
There are also some miscellaneous items that have been taken away by the technical department. "
Han Bin nodded. He had seen the photos of the cellar case before and knew the general situation.
"Do the villagers who rented the house have any impression of the suspect?"
Rao Jianguo shook his head. "The house was rented last year. At that time, the suspect was still wearing a mask. Some time ago, the villagers had almost no impression of the person who rented the house. It's hard to provide any valuable clues."
Han Bin said, "In other words, a year ago, they already told the planner that they wanted to commit a crime.
Ma Youcai's confession of choosing the crime scene first and finding random targets should be a lie. "
Rao Jianguo said, "You suspect that they have another motive for kidnapping Huang Yingying."
"You'll have to ask Huang Zean." Han Bin snorted. In his opinion, Huang Zean didn't play a good role in the case.
First of all, he should have called the police immediately after Huang Yingying was kidnapped.
Secondly, he shouldn't have interfered with the police investigation, and he shouldn't have pestered the municipal bureau to hand over the case to the provincial bureau.
Han Bin and Rao Jianguo hadn't known each other for a long time, but from their interactions and Rao Jianguo's understanding of the case, there was nothing wrong with Rao Jianguo's investigation methods and criminal investigation skills.
As for the plan to capture Ma Youcai, it couldn't be said that it was wrong. It could only be said that he chose the wrong time.
The case was urgent, and the hostages could be killed at any time. It wasn't wise to change the leader at this time and let the provincial bureau take over the case.
Take Han Bin for example. No matter how capable he was, he needed to understand the process of the case before he could make a further judgment.
Today, he did almost nothing else but understand the situation of the 8.29 case. Rao Jianguo also accompanied him the whole time, and the investigation of the case was almost at a standstill.
For the hostages, every day could affect their life and death.
After leaving Xiaoxuan Village, Han Bin suddenly asked, "Where did you find the red Porsche?"
Rao Jianguo asked, "Near the South Second Ring Highway. Do you want to take a look?"
"I'm not going." Han Bin responded and continued, "Captain Rao, please send me the surveillance footage of the kidnapping scene, the car abandonment scene, and the vicinity of Xiaoxuan Village."
"Okay, I'll get someone to sort it out later." Rao Jianguo agreed, but he didn't have much hope in his heart.
How could he not know the simplest cross-comparison? He had already asked someone to compare the surveillance footage of the three scenes, but they didn't find any suspicious people.
…
After returning to the office, Han Bin began to compare the surveillance footage of the three nearby scenes.
Among them, there were surveillance footage from Skynet and surveillance footage from shops. It was very cumbersome to compare multiple surveillance footage with each other.
The surveillance footage near the kidnapping scene and the car abandonment scene were all taken at night, and the lighting was not very good.
The surveillance footage near Xiaoxuan Village was relatively long. It had been more than half a month since August 29th.
Han Bin first looked at the surveillance footage near the kidnapping scene and the car abandonment scene. He had a general impression of the people who had been to the two scenes, and then looked at the surveillance footage near Xiaoxuan Village.
Among them, Han Bin found Ma Youcai's figure in the surveillance footage near the kidnapping scene and Xiaoxuan Village. However, Ma Youcai acted alone, and he didn't find any other accomplices.
At seven o 'clock in the evening, after checking a large number of surveillance footage, Han Bin found two suspicious figures.
One figure appeared at the kidnapping scene, and the other figure appeared in the surveillance footage near Xiaoxuan Village.
Han Bin named the two figures A and B.
Figure A had short hair, wore a gray T-shirt, wore a mask, and held a black leather bag in his right hand. He looked like a middle-aged man. At nine o 'clock in the evening, he appeared in the surveillance footage near the kidnapping scene.
Figure B had long curly hair, wore a woman's dress, and also wore a mask. He looked like a middle-aged woman.
In terms of appearance, they were two completely different people. There were significant differences in gender, clothing, and body shape. Even the way they walked was somewhat different.
However, after careful comparison, Han Bin found that the frequency of the two people's gait and body shape were very similar. Figure B walked more naturally, while Figure A seemed to walk a little deliberately. After a large number of video comparisons, the probability of these two figures being the same person was 70 to 80 percent.
The Quancheng Public Security Bureau also compared the surveillance footage near the three locations. The reason why they didn't find anything was probably because the suspects were in different locations and had completely different outfits. In addition, the light at night was not good, so it was extremely difficult to distinguish.
After that, Han Bin gathered his team members and ordered them to continue tracking these two suspicious figures. They wanted to see where these two people had been to. Who knows, they might be able to find new clues by following the clues.
Rao Jianguo looked at the two sets of videos carefully. "Captain Han, these two people's outfits are so different. How did you tell?"
Wang Chang said, "Captain Han is proficient in identifying footprints. You don't need to look at the face. You can tell if it's the same person just by looking at the way they walk."
Rao Jianguo nodded and didn't say anything else. He didn't know if he really believed him.
Bao Xing asked curiously, "Captain Han, can you tell her gender?"
Han Bin analyzed, "Judging from her body shape and walking posture, she should be a woman between forty and fifty years old."
